QoS/DSCP (the DiffServ model)
DSCP-ECN defines QoS at Layer 3 (Network Layer)� The Differentiated Services (DiffServ) model is
based on packet marking and router queuing disciplines. The marking is done by adding a eld to the
IP header, called the DSCP (Differentiated Services Codepoint)� This is a 6-bit field that provides 64
different class IDs� It gives an indication of how a given packet is to be forwarded, known as the Per Hop
Behavior (PHB)� The PHB describes a particular service level in terms of bandwidth, queueing theory,
and dropping (discarding the packet) decisions� Routers at each network node classify packets according
to their DSCP value and give them a particular forwarding treatment; for example, how much bandwidth
to reserve for it�
Below are the setting options of DSCP (DiffServ Codepoint)� Specify the DSCP value for each application
(0~63)�
